Wound covering and method for treating a wound
A wound covering is described herein and which includes a flexible substrate having first and second portions which are affixed together, and moveable one relative to the other, and wherein the second portion is, at least in part, optically transparent, and permits the viewing of a wound site on a patient; and an at least partially rigid member mounted on the first portion, and extends outwardly relative to the first portion.
The present invention relates to a wound covering, and method for treating a wound, and more specifically to a wound covering which includes a pressure pad region; and an absorbent wound covering portion which can be observed by a care giver when the wound covering portion is being utilized on a patient.
BACKGROUND OF THE INVENTIONThe prior art is replete with numerous examples of various wound coverings, including hemostats of various designs, and which have been utilized through the years to aid clinicians in the treatment of various maladies. For example, with respect to various wound dressings, various designs have been marketed which allow a clinician, or other health care provider to monitor the site of a wound following a surgical intervention. For example, the Office's attention is directed to the hemostatic bandage marketed by a company identified as Vascular Solutions under the trademark D-STAT DRY CLEAR and which provides a clear bandage which allows for the clear visualization of a wound site. This product has reinforced borders which reportedly provide for more precise placement of the bandage in comparison to other clear bandages. Further, other pressure assisted dressings are marketed currently for various clinical applications. For example, the Office's attention is directed to the pressure assisted dressing marketed under the trademark SAFEGUARD and which is provided by a company named DataScope. The SAFEGUARD pressure assisted dressing provides an adhesive portion which is attached to the skin of a patient, and an inflatable balloon which can apply an adjustable amount of pressure in order to assist in the closure of a wound site. Still further, the SAFEGUARD product allows a clinician to continue to visualize the wound site while pressure is being applied.
In addition to the foregoing products that are currently available for purchase, it has long been known to provide various hemostat arrangements which provide a means by which a flowable substance may be provided to the hemostat while it is being utilized. In this regard, the Office's attention is directed again to the commercial product provided by the company Vascular Solutions, and which is identified by the trademark, “D-STAT Flowable Hemostat”.
While the prior art devices and methodologies used heretofore have been widely embraced and are generally successful for their intended purposes, clinicians have continued to search for a convenient wound covering which provides a means by which pressure can be selectively applied, and thereafter the wound site can be monitored while also providing a convenient means whereby selected medicaments may be provided to the wound site without removing the wound covering.
A wound covering and method for treating a wound is the subject matter of the present application.
SUMMARY OF THE INVENTIONA first aspect of the present invention relates to a wound covering which includes a flexible substrate having first and second portions which are affixed together, and moveable one relative to the other, and wherein the second portion is at least, in part, optically transparent, and permits the viewing of a wound site on a patient; and an at least partially rigid member mounted on the first portion, and extending outwardly relative to the first portion.
Another aspect of the present invention relates to a wound covering, which includes a flexible substrate having an inwardly facing surface which is coated, at least in part, by an adhesive, and an outwardly facing surface, and wherein the flexible substrate has a first portion, and a second portion, and wherein the second portion is, at least in part, optically transparent, and is operable to cover a site of a wound on a patient's body; a pressure pad mounted on the inwardly facing surface of the first portion of the flexible substrate, and which is oriented in rested relation on a patient's body, and wherein a clinician applies force to the pressure pad to achieve a desired medical outcome; and an absorbent wound covering portion which is oriented in covering relation relative to the site of the wound on the patient's body, and which is secured in place by the second portion of the flexible substrate.
Still further, the present invention relates to a method for treating a wound, which includes the steps of providing a flexible substrate having opposite inwardly and outwardly facing surfaces and which defines a first portion, and a second portion which are moveably coupled together; applying an adhesive to at least a portion of the inside facing surface of the flexible substrate; mounting a pressure pad on the inside facing surface of the first portion of the flexible substrate; positioning the pressure pad in an anatomically correct position on a patient's body and adhesively affixing the first portion of the flexible substrate to the patients body; after the step of positioning the pressure pad, orienting the second portion of flexible substrate in spaced relation relative to the patient's body; after the step of orienting the second portion of the flexible substrate in spaced relation relative to the patient's body, implementing a medical procedure which creates a wound site in the patient's body which is located in spaced relation relative to the pressure pad; moving the second portion of the flexible substrate into covering relation relative to the wound site, and adhesively affixing it to the patient's body; and positioning an absorbent wound covering portion over the wound site, and in sandwiched relation therebetween the patient's body, and the inside facing surface of the second portion of the flexible substrate prior to adhesively affixing the second portion of the flexible substrate to the patient's body.
These and other aspects of the present invention will be described in greater detail hereinafter.
